Research Interests

My research career so far has focussed on the investigation of novel materials for semiconductor device applications. This has included solar cells, lasers & LED devices. My work has often involved the synthesis and characterisation of new semiconductor materials using a variety of techniques. In addition to my device work I have automated new experimental setups and data analyses.

These two table of contents figures highlight some of my research expertise (synthesising and characterising new materials and applying these materials to new devices).

Experimental Skills

• Materials Synthesis: Solution Processed Semiconductors, Nanocrystal Synthesis
• Device Fabrication and Optimisation: LEDs, Lasers, Photovoltaics
• Electrical Characterisation: Current-Voltage Analysis, Accelerated Aging, Encapsulation
• Thin Film Characterisation: XRD, SEM, EDX, Optical Microscopy, STM, AFM, Profilometry
• Automation: Labview, Arduino, Writing Drivers, Python
